9.3 Battery replacement
The E3 uses a 9V Lithium Sulphur Dioxide battery pack, McMurdo type 82-140.
Typically this will have to be replaced every 5 years. The exact battery expiry date is
marked on the rear of the E3 lens dome and if you have a full enclosure it is also
marked on the outside of the enclosure. The battery expiry date should be checked
regularly. You will need to replace the battery when...
• The expiry date has been reached.
• The E3 has been used in an emergency situation.
• A false activation exceeds 2 hours of use.
The battery is a one shot device. It is not rechargeable or user replaceable. Battery
replacement must be carried out by a McMurdo approved service agent. Lithium
batteries have special disposal requirements. Never incinerate a Lithium battery.
Never dispose of one at sea. Your service agent will deal with battery disposal.
9.4 Servicing
All servicing must be carried out by a McMurdo approved service agent. Always call
your nearest agent and talk to their service department before returning suspect
equipment. You can find your nearest service agent from...
• The McMurdo web site :
• Contacting McMurdo direct (see warranty page).
9.5 Transportation
The E3 has no special transportation requirements. Its Lithium battery has been
tested under the "transportation of dangerous goods" regulations and has been
declared as non-hazardous for transportation purposes.
9.6 GMDSS inspections
If your vessel is subject to GMDSS regulations then you can expect to get regular
visits from ship surveyors enforcing national legislation. They will check the expiry
dates and activate the EPIRB to prove it really works and they will read the identity
message stored inside the EPIRB to check that you have registered it properly.
Leisure vessels are not subject to these inspections. However, in some countries
passenger and fishing vessels are covered by the legislation.
